When does shop at Yoshida 5th station close?

Hi all, I'll be climbing Mount Fuji next week and heard about the walking sticks you can buy at the souvenir shop and have branded at each station. I plan to do the sunrise hike and was wondering if anybody knew when the gift shop at 5th station closes so that I could make sure to be there to buy a hiking stick on time.

Also if anybody knows whether the branding is done through the night that would be great go know as well!

Thanks!

I just quickly googled in Japanese and found that the gift shop closes at 17:00.
I couldn't get your second question, sorry.
Hope you enjoy your time in Fuji san.
